(1) Except as otherwise provided in subsection (2) of this section, a proceeding brought by a presumed parent, the person with a parent-child relationship with the child, or another individual to adjudicate the parentage of a child having a presumed parent must be commenced not later than four years after the birth of the child. If an action is commenced more than two years after the birth of the child, the child must be made a party to the action.

(2) A proceeding seeking to disprove the parent-child relationship between a child and the child's presumed parent may be maintained at any time if the court determines that the presumed parent and the person who has a parent-child relationship with the child neither cohabited nor engaged in sexual intercourse with each other during the probable time of conception and the presumed parent never held out the child as his or her own.
